Liney Halo Custom 5 Cylinder Radial Steam Engine

To purcchas this engine please visit http://www.minicastings.com

This is the HALO five cylinder radial. Liney has been developing it as time allowed over the last three years. The intent was to make an external combustion (steam/compressed air) design that mimicked the operation of real radial aircraft engines as close as possible. It has cams on the crank which operate the pushrods and in turn the rocker arms and the very unique ball bearing valves. It has five 3/8th inch pistons linked to the single crank via a master rod and connecting rods just as would be expected in a full size radial. Best of all, the design allows you to see nearly every moving part while the engine is running. Even the cams and pushrod end bearings can be seen. Unlike a normal four stroke radial, every piston "fires" every revolution. Five power strokes per revolution! This engine is completed and ready to run.

Some dimensions:
.375 pistons with .375 stroke (square engine)
The engine is just under 5 inches overall OD
The cylinders are .75 inches OD
The crankcase is 1.65 OD
The Drive shaft is 1/4"

It was much better mounted to a stand that could contain it, then we heard only the engine, and not terrible vibrations.

I kept waiting for him to get his hand in the blades, blood splattering everywhere.

dosent seem very balenced O.o

[SoppeliSoppa]

PUT THAT TO RC PLANE?

[capman911]

What keeps it lubricated. Do you mix a little oil in with the air? How about the push rod assemble what lubricates it? Nice design.

[mrTreekiller666]

i would make an rc plane like that and have a thing of compressed air to fly it

[gtoddv]

@awlingbeck They are using compressed air for the demo, a very common way to demo as it allows you to get an unobstructed view.

[DrReaper]

How much torque does it produce?

[awlingbeck]

These claim to be steam engines but where is the steam?

[Estrodile]

@mogeroithe Me too! Perhaps the blades are plastic?

[popsaka1]

So what kind of air supply is needed, and can it power anything and can it be converted to an internal combustion engine????

[jimbronaugh]

what kind of work can this engine perform. How much horsepower?
